Put the eggs in a bowl with all but 1/4 cup of the Parmesan cheese, most of the parsley and one of the ramen seasoning packets (toss the other two). Whisk it all up together and set aside.
Meanwhile, cook the bacon in a large deep skillet until crispy. Scoop out with a slotted spoon and drain on paper towels, leaving the drippings in the skillet.
Cook ramen according to package directions until done, scooping out a cup of pasta water at the end.
Add the hot cooked ramen to the skillet with the bacon drippings, followed by the butter, the egg mixture and the bacon and toss to coat – the heat of the ramen is going to cook that egg mixture just the right amount. Sprinkle in some pepper, and if you think the sauce needs a little loosening up, drizzle in some of that pasta water that you saved. Sometimes I do this and sometimes I don’t.
Divide among warmed plates, sprinkle with remaining Parmesan and parsley and serve!
